Why Are Yewdale
Blackout Blinds So Superior?

When your customer wants total darkness, the YewdaleDefiant® blackout blind range is the ultimate. Easily distinguishable from other blinds by its sleek, black or white powder coated hardware and well-enclosed fabric, our blackout blinds are admired in schools, hospitals and even cinema rooms around the country. Let’s take a look at what makes this blackout blind range so effective.

One of the most notable elements of the Yewdale blackout blind range is the solid, all-encompassing unit. It seals the window against light in all parts.

Some retail ‘blackout blinds’ on the market are only so due to the fabric they use. A blackout fabric will stop light travelling through it, but if light can seep around the edge or between the brackets, the pursuit of total darkness is dashed. Negating this and stamping its authority on the subject, Yewdale’s blackout blinds have a headbox, side channels and bottom channel. These fasten to the wall and around the window or within the recess, essentially boxing in the window and eliminating light.

The choice of fabric is vital. The blackout properties of a blind would be totally eliminated if we weren’t fussy about what fabric we used in our systems. The fabric we recommend is complete blackout: Roach, Dart and Medway. Roach and Dart are made from PVC and Medway is made from polyester. Blackout fabrics are typically denser and have a reflective coating on the back which prevents light penetrating the fabric. 


The fabric comes with windcheat bars across the middle. This reinforces the fabric and limits the chance of the fabric being blown out of the side channels by the wind of an open window. This layer of attention to detail is what makes these blackout blinds so superior. For others, a slight breeze from an open window can cause the fabric to billow and flap, removing the blackout properties as sunlight seeps around the edges. A windcheat bar prevents this, holding the fabric fast in the side channels and protecting it from the perils of an open window.



Whilst on the subject of side channels and attention to detail, it is worth discussing the pile seal used to block light from creeping through. Great effort has been taken to ensure that no light can enter the room through the side channels. The difference between a standard cassette with side channels and a blackout blind is the pile seal used inside the side channels. This fluffy seal disrupts the light that may make it into the side channel whilst not restricting the blind’s movement. Simple, yet so effective.


When it comes to the mechanism on a blackout blind, you’ll notice we don’t use chains. A gap in the headbox to allow the chain through would compromise the blind’s blackout properties. Instead we use crank or motor operated systems that don’t require large gaps in the blind. Yewdale has gone to every length to ensure light is blocked at every opportunity.


The reason YewdaleDefiant® blackout blinds are the superior system on the market is not simply through claims and bold statements, but because it is tried and tested. Tweaks and adjustments have been made throughout its development based on client feedback. Yewdale’s range of blackout blinds is an example of our commitment to quality, creating blinds that serve a purpose, and make sure that purpose is fulfilled perfectly.
